We built this HD inspired concept prototype so he can show his biker buddies that vaporizers hit harder than Hell's Angel's. It's a high power, high airflow power house that takes advantage of the massive thermal capacity of the Zion heater. Simply hit it till ya see vapor and then let off the gas and draw as fast as you can to keep ahead of the raw blistering Power stored in the Zion heater. We call it capacitive discharge vaping and it's not for the faint of heart. This is True American bad ass brass knuckle power that just might be up your alley. You man enough for a Jacked up Zion? @HD Springer sure the hell is. She's on her way way, show them brothers of yours how we roll RBT style. Rapid convection vapor on steroids that will punch you in the face so hard you will swear it was a dab.
